A title update to the Xbox 360 version of Fallout: New Vegas, to prepare the game for the upcoming Honest Hearts DLC should not be accepted until a replacement update goes live later this evening, Bethesda Softworks said.

The update currently being served freezes gamesave data, making it unplayable. That's kind of a bitch, especially if you've put 40 hours of work into this.

Bethesda spotted the problem after the original update went live earlier today, then advised gamers to reject that outright. A playable update for English versions of the game should go live later tonight, Bethesda said. Updates in other languages will take a little longer. "When we have a better estimate of what that will be, we'll let you know," the studio says. The update will unfreeze any bricked gamesave.

Bethesda is posting updates on the situation at the link below; you can check in there. When the fix is reported we'll update here.
